Description

Technical Field

[0001] The following relates generally to wireless communications and, more particularly, to resource block set allocation for sub-band full-duplex operation. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices, which may also be referred to as user equipment (UE).

[0003] Wireless communications can be used in bandwidths across both licensed and unlicensed radio spectrum bands. The bandwidth can be divided into multiple resource block (RB) sets. When a UL RB set is adjacent to a DL RB set, or when an RB set for one UE is adjacent to another RB set for another UE, these RB sets can use guard bands to reduce interference. An efficient means of signaling the configuration of RB sets and the guard bands for these RB sets is required. Summary of the Invention

[0004] The described technology relates to improved methods, systems, devices and apparatus for supporting resource block set allocation for sub-band full-duplex operation. In general, the described technology provides a configuration of a base station and a configuration of multiple resource block sets that generate a radio spectrum band. The base station can communicate one or more aspects of the configuration to a user equipment (UE). The base station can send a downlink control information message to the UE, which indicates the communication direction of the resource block set for each resource block set in the multiple resource block sets. In some cases, the UE can communicate with the base station using one or more resource block sets in the multiple resource block sets according to the one or more communication directions indicated by the received downlink control information message. The one or more communication directions can correspond to corresponding resource block sets in the multiple resource block sets.

[0052] The present technology provides improvements to resource block set allocation based on control information. The present technology includes resource block set allocation for sub-band full-duplex operation. In some examples, full-duplex operation can be used for bandwidth in licensed (e.g., New Radio (NR)) and unlicensed (e.g., NR Unlicensed (NR-U)) radio spectrum bands. In some cases, the bandwidth can be divided into multiple resource block (RB) sets. For full-duplex operation, a resource block set can be used and configured as uplink (UL) or downlink (DL) for a period of time. When a UL resource block set is adjacent to a DL resource block set, these resource block sets can also use guard bands to reduce interference. In addition, for unlicensed bandwidth, only a subset of the resource block sets of the bandwidth can be active at a time. The present technology provides an efficient means of signaling a resource block set configuration, wherein the resource block set configuration includes whether the resource block set is UL or DL, whether the resource block set is available, and the guard band configuration of the resource block set. The present technology provides configurations for unlicensed bandwidth (e.g., configurations where only a subset of the resource block sets are available).

[0053] The present techniques include providing information regarding resource block sets based on consideration of full-duplex operation in both licensed bands (e.g., for NR) and unlicensed bands (e.g., for NR-U). In some cases, the present techniques include the base station providing an indication to the UE of the communication direction (e.g., UL or DL) for the resource block set. In some cases, the present techniques include the base station providing an indication to the UE of the availability of the resource block set (e.g., a first resource block set is available, a second resource block set is not available, etc.).

[0054] In some examples, the present technology introduces a directional bitmap (e.g., transmitted in DCI format 2_0). In some examples, the directional bitmap can be based on a shared bitmap used for NR-U to indicate the channel occupancy time for each LBT subband. However, the directional bitmap can be configured to indicate which resource block set is DL and which resource block set is UL (e.g., 0 for UL, 1 for DL, or vice versa). In some cases, when two adjacent resource block sets are DL, the guard band between them is of the DL guard band type. If two adjacent resource block sets are UL, the guard band between them is of the UL guard band type. The DL guard band can be configured to have a different size in frequency than the UL guard band. When one resource block set is UL and the next is DL, the guard band follows the UL / DL configuration respectively. In some cases, knowledge of the resource block set can be applied to the transmission of scheduling and configuration between the UE and the base station (e.g., as in NR-U), but with the present technology, the bits in the bitmap are treated with a new interpretation.

[0055] In some examples, the second bitmap and the first bitmap may be included in the signaling (e.g., in DCI format 2_0). The first bitmap may indicate the communication direction of the resource block set (e.g., which resource block set is DL, which resource block set is UL, etc.), and the second bitmap may indicate the resource block set availability (e.g., which resource block set is available for transmission, which may be based on the LBT results). If two adjacent resource block sets are DL, the guard band between them may be of DL type. If two adjacent resource block sets are UL, the guard band between them may be of UL type, and its size may be different from the DL type. If one resource block set is DL and the next is UL, the guard bands follow the full-duplex UL / DL configuration respectively. When a resource block set is not available for transmission, the available adjacent resource block sets with the same direction (UL or DL) will follow the UL / DL guard bands for NR-U. Therefore, the present technology can provide four types of resource block sets based on licensed bands and unlicensed bands. For DL ​​resource block sets and UL resource block sets in unlicensed bands, the current definition in NR-U is followed. For the DL resource block set of the full-duplex band and the UL resource block set of the full-duplex band, a new definition associated with the first bitmap is followed.

[0056] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further described in the context of a wireless communication subsystem. Aspects of the present disclosure are initially described in the context of a wireless communication environment (e.g., the environment of a wireless communication system). Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to resource block set allocation for sub-band full-duplex operation.

[0057] Figure 1An example of a wireless communication system 100 supporting resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0058] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of different forms or capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which a UE 115 and base station 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support communication of signals according to one or more radio access technologies.

[0059] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. The UEs 115 may be devices of different forms or capabilities. Figure 1 Some example UEs 115 are shown in FIG. The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 shown.

[0060] The base stations 105 can communicate with the core network 130, or with each other, or both. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other via the backhaul links 120 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 can be or include one or more wireless links.

[0061] The one or more base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga NodeB (any of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable terminology.

[0062] UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0063] The UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, such as Figure 1 shown.

[0064] The UE 115 and the base station 105 can wirelessly communicate with each other via one or more communication links 125 over one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 can include a portion of a radio spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with the UE 115. Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0065] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel raster for discovery by a UE 115. A carrier may operate in a standalone mode, where initial acquisition and connection may be performed by a UE 115 via the carrier, or in a non-standalone mode, where a connection is anchored using a different carrier (e.g., the same or different radio access technology).

[0066] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0067] A carrier can be associated with a particular bandwidth of radio spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of bandwidths determined for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). The devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a particular carrier bandwidth, or can be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0068] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may be composed of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate of the UE 115. Wireless communication resources may refer to a combination of radio spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with the UE 115.

[0069] One or more parameter sets for a carrier may be supported, where the parameter set may include subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP may be active for a carrier at a given time, and communications by the UE 115 may be limited to the one or more active BWPs.

[0070] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported Discrete Fourier Transform (DFT) size may be indicated. Time intervals for communication resources may be organized according to radio frames, where each radio frame has a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0071] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include multiple symbol periods (e.g., depending on the length of a cyclic prefix pre-appended to each symbol period). In some wireless communication systems 100, the time slot may be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0072] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0073] Physical channels can be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels can be multiplexed on a downlink carrier using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) of a physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more UEs 115 can monitor or search for control information in a control region according to one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information of a control information format having a given payload size. A search space set can include a common search space set configured for transmitting control information to multiple UEs 115, and a UE-specific search space set for transmitting control information to a specific UE 115.

[0074] In some examples, base stations 105 can be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0075] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably herein.

[0076] In some examples, UE 115 can also communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UEs 115 in the group can be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, the group of UEs 115 communicating via D2D communication can utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

[0077] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entities may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management, for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be transmitted via user plane entities, which may provide IP address allocation and other functions. The user plane entities may be connected to network operator IP services 150. Operator IP services 150 may include access to the Internet, intranet(s), IP multimedia subsystems (IMS), or packet-switched streaming services.

[0078] Some network devices, such as base stations 105, may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with a UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., base station 105).

[0079] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficient to enable a macro cell to provide service to a UE 115 located indoors. Transmission of UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) compared to transmission using smaller frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0080] The wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, the wireless communication system 100 can employ License Assisted Access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio spectrum band, devices such as base stations 105 and UEs 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band can be based on a carrier aggregation configuration in combination with component carriers operating in a licensed band (e.g., LAA). Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0081] A base station 105 or a UE 115 may be equipped with multiple antennas that may be used to employ techniques such as transmit diversity, receive diversity, multiple-input, multiple-output (MIMO) communications, or beamforming. The antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays or antenna panels that may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with a base station 105 may be located at different geographic locations. A base station 105 may have an antenna array having multiple rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Similarly, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support radio frequency beamforming for signals transmitted via the antenna ports.

[0082] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0083] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate through logical channels. The media access control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission of the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection between the UE115 and the base station 105 or the core network 130 that supports the radio bearer of the user plane data. At the physical layer, the transport channel can be mapped to the physical channel.

[0084] In some examples, Figure 1 The UE 115 can be configured based on the configuration (e.g., resource block set configuration) and Figure 1 105. In some examples, the base station 105 may determine the configuration of multiple resource block sets of a radio spectrum band. In some cases, the radio spectrum band may be a licensed radio spectrum band or an unlicensed radio spectrum band. In some examples, the base station 105 may send a downlink control information message to the UE 115, the downlink control information message indicating a communication direction for each resource block set in the multiple resource block sets. In some cases, the UE 115 may receive the downlink control information message and determine one or more aspects of the configuration of the multiple resource block sets in the radio spectrum band based on the information indicated in the downlink control information message. In some cases, the downlink control information message may indicate one or more communication directions (e.g., uplink (UL), downlink (DL)) associated with the multiple resource block sets, or may indicate available resource block sets and unavailable resource block sets of the multiple resource block sets, or may indicate both. In some cases, the UE 115 may communicate with the base station 105 using one or more resource block sets in the multiple resource block sets based on the information indicated in the downlink control information message.

[0085] Figure 2 An example of a wireless communication subsystem 200 that supports resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. In some examples, the wireless communication subsystem 200 can implement aspects of the wireless communication system 100. In some cases, the radio spectrum band of the wireless communication subsystem 200 can be or operate in a licensed radio spectrum band. The wireless communication subsystem 200 can include a UE 115-a and a base station 105-a, which can be examples of a UE 115 or a base station 105, as described above with reference to FIG. Figure 1 The wireless communication subsystem 200 may also include a downlink 205 and an uplink 210. The base station 105-a may use the downlink 205 to transmit control and data information to the UE 115-a. The UE 115-a may use the uplink 210 to transmit control and data information to the base station 105-a. In some cases, the downlink 205 may use different time and / or frequency resources than the uplink 210.

[0086] In the example shown, base station 105-a may transmit downlink control information (DCI) 215 to UE 115-a via downlink 205. As shown, DCI 215 may include a bitmap 220 (e.g., one or more bitmaps). In some cases, DCI 215 may include two or more bitmaps comprising bitmap 220. In some cases, bitmap 220 may include a direction bitmap indicating a communication direction for each resource block set in a plurality of resource block sets. In some cases, bitmap 220 may include an availability bitmap indicating which resource block sets in a plurality of resource block sets are available and which resource block sets in a plurality of resource block sets are not available.

[0087] In some cases, the DCI 215 indicates a slot format. In some examples, the DCI 215 may be scrambled by a slot format indication radio network temporary identifier (SFI-RNTI). In some examples, the UE 115-a may communicate with the base station 105-a according to a configuration associated with the wireless communication subsystem 200 (e.g., a resource block set configuration). In some cases, the base station 105-a may configure or select the configuration and communicate the configuration to the UE 115-a. In some examples, the base station 105-a may indicate the configuration to the UE 115-a in the DCI 215.

[0088] In some examples, base station 105-a may determine a configuration for each resource block set in a plurality of resource block sets for a radio spectrum band. In some cases, the configuration may indicate a communication direction for each resource block set in the plurality of resource block sets. The configuration may indicate that a first resource block set in the plurality of resource block sets has an uplink communication direction, and the configuration may indicate that a second resource block set in the plurality of resource block sets has a downlink communication direction, and so on. In some examples, bitmap 220 may indicate the uplink / downlink communication direction of the resource block sets. In some examples, a binary 0 in bitmap 220 may indicate an uplink communication direction for the resource block set, and a binary 1 in bitmap 220 may indicate a downlink communication direction for the resource block set. In some examples, a binary 1 in bitmap 220 may indicate an uplink communication direction for the resource block set, and a binary 0 in bitmap 220 may indicate a downlink communication direction for the resource block set.

[0089] In some examples, the configuration may indicate which resource block sets of the plurality of resource block sets are available and which resource block sets of the plurality of resource block sets are unavailable. The configuration may indicate that a first resource block set of the plurality of resource block sets is available and a second resource block set of the plurality of resource block sets is unavailable, and so on. In some examples, bitmap 220 may indicate the availability of resource block sets. In some examples, a binary 0 in bitmap 220 may indicate that a resource block set is available, and a binary 1 in bitmap 220 may indicate that a resource block set is unavailable. In some examples, a binary 1 in bitmap 220 may indicate that a resource block set is available, and a binary 0 in bitmap 220 may indicate that a resource block set is unavailable.

[0090] In some cases, UE 115-a may receive DCI 215 and determine one or more aspects of the configuration of the multiple resource block sets based on information indicated in DCI 215. In some cases, DCI 215 may indicate a communication direction for the multiple resource block sets (e.g., a communication direction for one or more resource block sets of the multiple resource block sets). In some cases, DCI 215 may indicate resource block set availability (e.g., which resource block sets of the multiple resource block sets are available, or which resource block sets of the multiple resource block sets are unavailable, or both). In some cases, DCI 215 may indicate both a communication direction and resource block set availability associated with the multiple resource block sets.

[0091] In some cases, the UE 115-a may communicate with the base station 105-a based on a configuration (e.g., a resource block set configuration) associated with the wireless communication subsystem 200. In some examples, the UE 115-a may communicate with the base station 105-a based on information indicated in the DCI 215. In some instances, the UE 115-a may communicate with the base station 105-a based on using one or more resource block sets from a plurality of resource block sets based on the information indicated in the DCI 215. In some instances, the UE 115-a may communicate with the base station 105-a based on one or more communication directions for the plurality of resource block sets indicated in the DCI 215. In some instances, the UE 115-a may communicate with the base station 105-a based on resource block set availability for the plurality of resource block sets indicated in the DCI 215. In some instances, UE 115 - a may communicate with base station 105 - a based on one or more communication directions of the plurality of resource block sets indicated in DCI 215 and resource block set availability.

[0092] Figure 3An example of an environment 300 that supports resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. In some examples, the environment 300 can implement aspects of the wireless communication system 100. In some cases, the environment 300 depicts an UL / DL guard band configuration for an environment operating in a licensed radio spectrum band. In some cases, a base station (e.g., Figure 1 or Figure 2 The base station 105) can send a signal to the UE (e.g., Figure 1 or Figure 2 The UE 115 is signaled to define the UL / DL guard band configuration that defines the resource block set and aspects of the guard band configuration within the cell (eg, frequency size or bandwidth, etc.).

[0093] In the example shown, environment 300 may include a guard band configuration 305 and a guard band configuration 310 for a licensed radio spectrum band. Guard band configuration 305 depicts the configuration of a set of DL resource blocks and a DL guard band in the licensed radio spectrum band. Guard band configuration 310 depicts the configuration of a set of UL resource blocks and a UL guard band in the licensed radio spectrum band. In some examples, the radio spectrum of environment 500 may use 20 MHz as a basic channel access unit. This basic channel access unit may be referred to as an LBT bandwidth. In some cases, the available resource blocks in each LBT bandwidth may be referred to as a resource block set.

[0094] As shown, guard band configuration 305 may include DL resource block set 315-a, DL resource block set 315-b, DL resource block set 315-c, and DL resource block set 315-d. As shown, DL guard band 320-a and DL guard band 325-a may be located between DL resource block set 315-a and DL resource block set 315-b, DL guard band 320-b and DL guard band 325-b may be located between DL resource block set 315-b and DL resource block set 315-c, and DL guard band 320-c and DL guard band 325-c may be located between DL resource block set 315-c and DL resource block set 315-d.

[0095] As shown, guard band configuration 310 may include UL resource block set 330-a, UL resource block set 330-b, UL resource block set 330-c, and UL resource block set 330-d. As shown, UL guard band 335-a and UL guard band 340-a may be located between UL resource block set 330-a and UL resource block set 330-b, UL guard band 335-b and UL guard band 340-b may be located between UL resource block set 330-b and UL resource block set 330-c, and UL guard band 335-c and UL guard band 340-c may be located between UL resource block set 330-c and UL resource block set 330-d.

[0096] In some examples, a DL resource block set (e.g., DL resource block set 315-a, etc.) can be derived from intra-cell DL guard band signaling (e.g., the configuration of DL guard band 320-a). In some examples, a UL resource block set (e.g., UL resource block set 315-a, etc.) can be derived from intra-cell UL guard band signaling (e.g., the configuration of UL guard band 320-a). In some examples, the DL guard band may not be aligned with the UL guard band (e.g., aligned in frequency). In some examples, the DL resource block set or the UL resource block set or both may not be aligned with the 20 MHz basic channel access unit of the LBT bandwidth.

[0097] As shown in the figure, DL resource block set 315-a can be adjacent to DL protection band 320-a; DL resource block set 315-b can be adjacent to DL protection band 325-a and DL protection band 320-b; DL resource block set 315-c can be adjacent to DL protection band 325-b and DL protection band 320-c; DL resource block set 315-d can be adjacent to DL protection band 325-c and DL protection band 320-d.

[0098] As shown in the figure, UL resource block set 330-a can be adjacent to UL protection band 335-a; UL resource block set 330-b can be adjacent to UL protection band 340-a and UL protection band 335-b; UL resource block set 330-c can be adjacent to UL protection band 340-b and UL protection band 335-c; UL resource block set 330-d can be adjacent to UL protection band 340-c and UL protection band 335-d.

[0099] In some examples, each DL guard band can be configured to have a certain frequency size or bandwidth (e.g., signaled in the downlink control information). In some examples, each UL guard band can be configured to have a certain frequency size or bandwidth (e.g., signaled in the downlink control information). In some examples, the frequency size of the DL guard band can be different from the frequency size of the UL guard band. In some cases, when the base station is performing all DL or no DL transmission on two or more consecutive resource block sets, or the UE is performing all UL or no UL transmission on two or more consecutive resource block sets, the guard band can have zero frequency size or zero bandwidth.

[0100] Figure 4 An example of an environment 400 supporting resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. In some examples, environment 400 can implement aspects of wireless communication system 100. In the example shown, environment 400 can include a guard band configuration 405 and a guard band configuration 410 for a licensed radio spectrum band. Guard band configuration 405 can include multiple resource block sets. Guard band configuration 410 can include multiple resource block sets.

[0101] As shown, guard band configuration 405 may include UL resource block set 415-a, UL resource block set 415-b, DL resource block set 415-c, and DL resource block set 415-d. As shown, UL guard band 420-a and UL guard band 425-a may be located between UL resource block set 415-a and UL resource block set 415-b, UL guard band 420-b and DL guard band 425-b may be located between UL resource block set 415-b and DL resource block set 415-c, and DL guard band 420-c and DL guard band 425-c may be located between DL resource block set 415-c and DL resource block set 415-d.

[0102] As shown, guard band configuration 410 may include DL resource block set 430-a, DL resource block set 430-b, UL resource block set 430-c, and DL resource block set 430-d. As shown, DL guard band 435-a and DL guard band 440-a may be located between DL resource block set 430-a and DL resource block set 430-b, DL guard band 435-b and UL guard band 440-b may be located between DL resource block set 430-b and UL resource block set 430-c, and UL guard band 435-c and DL guard band 440-c may be located between UL resource block set 430-c and DL resource block set 430-d.

[0103] In some cases, the configuration of resource block sets can be applied to the transmission of scheduling and configuration between the UE and the base station based on a directional bitmap. In some cases, the directional bitmap can be sent in a downlink control information message (e.g., DCI format 2_0). In some cases, the directional bitmap can indicate which resource block set of guard band configuration 405 or guard band configuration 410 is DL and which resource block set is UL (e.g., 0 for UL and 1 for DL). In some cases, the bitmap size (e.g., the number of bits in the directional bitmap) can correspond to the number of resource block sets on the carrier.

[0104] Examples of directional bitmaps may include directional bitmap 445 and directional bitmap 450. As shown, directional bitmap 445 may be configured (e.g., by a base station) to indicate the configuration of guard band configuration 405, and directional bitmap 450 may be configured (e.g., by a base station) to indicate the configuration of guard band configuration 410.

[0105] In the example shown, the directionality bitmap 445 of the resource block sets of the guard band configuration 405 can be configured with a binary sequence

[0011] . In some examples, the least significant bit of the directionality bitmap 445 can be associated with the lowest frequency resource block set (e.g., UL resource block set 415-a) or the highest frequency resource block set (e.g., DL resource block set 415-d).

[0106] In the example shown, the least significant bit "0" of directional bitmap 445 indicates that UL resource block set 415-a is in the UL direction, and the next bit "0" indicates that UL resource block set 415-b is also in the UL direction. Therefore, because the two adjacent resource block sets are in the same direction, a UE receiving directional bitmap 445 can determine that UL guard band 420-a and UL guard band 425-a are each configured with zero frequency bandwidth, so that the bandwidth of UL guard band 420-a and DL guard band 425-a is also available for uplink communication in addition to the available bandwidth of UL resource block set 415-a and UL resource block set 415-b. A UE receiving directional bitmap 445 can determine that UL guard band 420-b is configured with the configuration of the permitted UL guard band of guard band configuration 310 (e.g., DL guard band 335-c, etc.) based on the next resource block set in the downlink direction (e.g., DL resource block set 415-c).

[0107] The next bit "1" of direction bitmap 445 indicates that DL resource block set 415-c is in the DL direction. The UE can determine that DL guard band 420-b is configured with the configuration of the permitted DL guard band of guard band configuration 305 (e.g., DL guard band 325-b, etc.) based on the previous resource block set in the uplink direction (e.g., UL resource block set 415-b).

[0108] The most significant bit "1" indicates that DL resource block set 415-d is in the DL direction. Therefore, because two adjacent resource block sets are in the same direction (e.g., DL resource block set 415-c and DL resource block set 415-d), the UE receiving direction bitmap 445 can determine that DL guard band 420-c and DL guard band 425-c are each configured with zero frequency bandwidth so that the bandwidth of DL guard band 420-c and DL guard band 425-c can also be used for downlink communication in addition to the available bandwidth of DL resource block set 415-c and DL resource block set 415-d.

[0109] In the example shown, the direction bitmap 450 of the resource block sets of the guard band configuration 410 can be configured with a binary sequence

[1101] . The least significant bit "1" of the direction bitmap 450 indicates that the DL resource block set 430-a is in the DL direction. The next bit "1" of the direction bitmap 450 indicates that the DL resource block set 430-b is also in the DL direction. Therefore, because two adjacent resource block sets are in the same direction (e.g., DL resource block set 430-c and DL resource block set 430-d), the UE receiving the direction bitmap 445 can determine that the DL guard band 435-c and the DL guard band 440-c are each configured with zero frequency bandwidth, so that in addition to the available bandwidth of the DL resource block set 430-c and the DL resource block set 430-d, the bandwidth of the DL guard band 435-c and the DL guard band 440-c can also be used for downlink communication.

[0110] The next bit "0" of direction bitmap 450 indicates that UL resource block set 430-c is in the UL direction. Because the previous resource block set (DL resource block set 430-b) is in the downlink direction, the UE can determine that UL guard band 440-b is configured with the configuration of the permitted UL guard band of guard band configuration 305 (e.g., UL guard band 340-b, etc.). Because the next resource block set (DL resource block set 430-d) is in the downlink direction, the UE can determine that UL guard band 435-c is configured with the configuration of the permitted UL guard band of guard band configuration 305 (e.g., UL guard band 335-c, etc.).

[0111] The most significant bit "1" indicates that DL resource block set 430-d is in the DL direction. Because the previous resource block set (UL resource block set 430-c) is in the uplink direction, the UE can determine that DL guard band 440-c is configured with the configuration of the permitted DL guard band of guard band configuration 305 (e.g., DL guard band 325-c, etc.).

[0112] As shown in the figure, when the communication direction of two adjacent resource block sets is DL (e.g., DL resource block set 415-c and DL resource block set 415-d), the guard band between them is a DL guard band type (e.g., DL guard band 420-c and DL guard band 425-c). When the communication direction of two adjacent resource block sets is UL (e.g., UL resource block set 415-a and UL resource block set 415-b), the guard band between them is a UL guard band type (e.g., UL guard band 420-a and UL guard band 425-a).

[0113] In some examples, the DL guard band (e.g., DL guard band 425-b) can be configured to have a different frequency size (e.g., a smaller bandwidth or a larger bandwidth) than the UL guard band (e.g., UL guard band 420-a). When the communication direction of one resource block set is UL (e.g., UL resource block set 415-b) and the communication direction of the next resource block set is DL (e.g., DL resource block set 415-c), the UL / DL transmission follows the UL / DL guard bands (e.g., UL guard band 420-b and DL guard band 425-b), respectively. When the communication direction of the resource block set is DL (e.g., DL resource block set 415-b) and the communication direction of the next resource block set is UL (e.g., UL resource block set 415-c), the DL / UL transmission follows the DL / UL guard bands (e.g., DL guard band 420-b and UL guard band 425-b), respectively. Therefore, the UL resource block set of the guard band configuration (e.g., UL resource block set 415-c of guard band configuration 410) can be derived separately from the DL resource block set of the same guard band configuration (e.g., DL resource block set 415-d of guard band configuration 410).

[0114] Figure 5 An example of an environment 500 supporting resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. In some examples, environment 500 can implement aspects of wireless communication system 100. In some cases, environment 500 depicts an UL / DL guard band configuration for an environment operating in a licensed radio spectrum band, an unlicensed radio spectrum band, or both.

[0115] In the example shown, environment 500 may include guard band configuration 505 and guard band configuration 510 for a licensed radio spectrum band. Guard band configuration 505 depicts the configuration of a set of DL resource blocks and DL guard bands in the licensed radio spectrum band. Guard band configuration 510 depicts the configuration of a set of UL resource blocks and UL guard bands in the licensed radio spectrum band. In some examples, the radio spectrum of environment 500 may use 20 MHz as a basic channel access unit (e.g., LBT bandwidth).

[0116] In the example shown, environment 500 may include guard band configuration 545 and guard band configuration 550 for an unlicensed radio spectrum band. Guard band configuration 545 depicts the configuration of a DL resource block set and a DL guard band in the unlicensed radio spectrum band. Guard band configuration 550 depicts the configuration of a UL resource block set and a UL guard band in the unlicensed radio spectrum band. In some examples, the radio spectrum of environment 500 may use 20 MHz as a basic channel access unit (e.g., LBT bandwidth).

[0117] As shown, guard band configuration 505 may include a DL resource block set 515 (e.g., 515-a, 515-b, 515-c, 515-d) for a licensed radio spectrum band, a DL guard band 520 (e.g., 520-a, 520-b, 520-c), and a DL guard band 525 (e.g., 525-a, 525-b, 525-c). As shown, DL guard band 520 and DL guard band 525 may be located between DL resource block set 515. Also as shown, guard band configuration 510 may include a UL resource block set 530 (e.g., 530-a, 530-b, 530-c, 530-d) for a licensed radio spectrum band, a UL guard band 535 (e.g., 535-a, 535-b, 535-c), and a UL guard band 540 (e.g., 540-a, 540-b, 540-c). As shown, UL guard band 535 and UL guard band 540 may be located between UL resource block sets 530 .

[0118] As shown, the guard band configuration 545 may include a DL resource block set 555 (e.g., 555-a, 555-b, 555-c, 555-d) for an unlicensed radio spectrum band, a DL guard band 560 (e.g., 560-a, 560-b, 560-c), and a DL guard band 565 (e.g., 560-a, 560-b, 560-c). As shown, the DL guard band 560 and the DL guard band 565 may be located between the DL resource block set 555. As also shown, guard band configuration 550 may include UL resource block sets 570 (e.g., 570-a, 570-b, 570-c, 570-d) for unlicensed radio spectrum bands, UL guard bands 575 (e.g., 575-a, 575-b, 575-c), and UL guard bands 580 (e.g., 580-a, 580-b, 580-c). As shown, UL guard bands 575 and UL guard bands 580 may be located between UL resource block sets 570.

[0119] In some examples, each of DL guard band 520, DL guard band 525, DL guard band 560, and DL guard band 565 can be configured to have a certain frequency size or bandwidth. In some cases, DL guard band 520 and DL guard band 525 of the licensed radio spectrum band can have the same or different frequency size as DL guard band 560 and DL guard band 565 of the unlicensed radio spectrum band.

[0120] In some examples, each of UL guard band 535, UL guard band 540, UL guard band 575, and UL guard band 580 can be configured to have a certain frequency size or bandwidth. In some cases, UL guard band 535 and UL guard band 540 configured for a licensed radio spectrum band can have the same or different frequency size as UL guard band 575 and UL guard band 580 configured for an unlicensed radio spectrum band.

[0121] Figure 6 An example of an environment 600 supporting resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. In some examples, environment 600 can implement aspects of wireless communication system 100. In some cases, environment 600 depicts an UL / DL guard band configuration for an environment operating in a licensed radio spectrum band, an unlicensed radio spectrum band, or both.

[0122] As shown, guard band configuration 605 may include UL resource block set 615-a, UL resource block set 615-b, DL resource block set 615-c, and DL resource block set 615-d. As shown, UL guard band 620-a and UL guard band 625-a may be located between UL resource block set 615-a and UL resource block set 615-b, UL guard band 620-b and DL guard band 625-b may be located between UL resource block set 615-b and DL resource block set 615-c, and DL guard band 620-c and DL guard band 625-c may be located between DL resource block set 615-c and DL resource block set 615-d.

[0123] As shown, guard band configuration 610 may include DL resource block set 630-a, DL resource block set 630-b, UL resource block set 630-c, and DL resource block set 630-d. As shown, DL guard band 635-a and DL guard band 640-a may be located between DL resource block set 630-a and DL resource block set 630-b, DL guard band 635-b and UL guard band 640-b may be located between DL resource block set 630-b and UL resource block set 630-c, and UL guard band 635-c and DL guard band 640-c may be located between UL resource block set 630-c and DL resource block set 630-d.

[0124] In some cases, the configuration of resource block sets can be applied to the transmission of scheduling and configuration between the UE and the base station based on the directional bitmap. In some cases, the directional bitmap and the availability map can be sent in a downlink control information message (e.g., DCI format 2_0). In some cases, the directional bitmap can indicate which resource block set of the guard band configuration 605 or guard band configuration 610 is DL and which resource block set is UL (e.g., 0 for UL and 1 for DL). In some cases, the availability map can indicate which resource block sets of the guard band configuration 605 or guard band configuration 610 are available. In some cases, the bitmap size (e.g., the number of bits in the directional bitmap) can correspond to the number of resource block sets on the carrier.

[0125] In the example shown, the base station may configure the directionality bitmap 650 of the resource block set of the guard band configuration 610 to have a binary sequence of

[1101] . In the example shown, the base station may configure the availability bitmap 660 of the resource block set of the guard band configuration 610 to have a binary sequence of

[0111] .

[0126] A UE that receives the direction bitmap 650 and the availability bitmap 660 may determine that the first bit (e.g., binary 1) of the direction bitmap 650 indicates that the first resource block set (e.g., DL resource block set 630-a) is in the downlink direction, and the first bit (e.g., binary 0) of the availability bitmap 660 indicates that the first resource block set is unavailable. Therefore, the UE may determine that the bandwidth of the DL resource block set 630-a and the DL guard band 635-a are unavailable based on the first bit (e.g., binary 0) of the availability bitmap 660. Based on the unavailability of the UL resource block set 630-a, the UE may determine that the DL guard band 635-a corresponds to an unavailable resource set, and thus the UE may determine that the DL guard band 635-a is also an unavailable bandwidth.

[0127] A UE receiving direction bitmap 650 and availability bitmap 660 can determine that the second bit (e.g., binary 0) of direction bitmap 650 indicates that the second resource block set (e.g., DL resource block set 630-b) is in the downlink direction, and that the second bit (e.g., binary 1) of availability bitmap 660 indicates that the second resource block set is available. Therefore, based on the fact that DL guard band 635-a corresponding to the unavailable resource block set and DL resource block set 630-b are available, the UE can determine that the configuration of DL guard band 640-a is configured using the configuration of the unlicensed UL guard band of guard band configuration 550 (e.g., UL guard band 580-a, etc.). The UE can also determine that the configuration of DL guard band 635-b is configured using the configuration of the licensed UL guard band of guard band configuration 510 (e.g., UL guard band 535-b, etc.).

[0128] A UE receiving direction bitmap 650 and availability bitmap 660 can determine that the third bit (e.g., binary 0) of direction bitmap 650 indicates that the third resource block set (e.g., UL resource block set 630-c) is in the uplink direction, and the third bit (e.g., binary 1) of availability bitmap 660 indicates that the third resource block set is available. Therefore, the UE can determine that the configuration of UL guard band 640-b is configured with the configuration of the permitted DL guard band (e.g., DL guard band 525-b) of guard band configuration 505.

[0129] A UE receiving direction bitmap 650 and availability bitmap 660 can determine that the fourth bit (e.g., binary 1) of direction bitmap 650 indicates that the fourth resource block set (e.g., DL resource block set 630-d) is in the downlink direction, and the fourth bit (e.g., binary 1) of availability bitmap 660 indicates that the fourth resource block set is available. Therefore, the UE can determine that the configuration of DL guard band 640-c is configured with the configuration of the permitted DL guard band of guard band configuration 505 (e.g., DL guard band 525-c).

[0144] The resource manager 910 may identify a configuration of a set of resource blocks of a radio spectrum band for the UE. In some cases, each resource block set in the set of resource blocks is included in a listen-before-talk bandwidth. In some cases, each listen-before-talk bandwidth is a bandwidth portion.

[0145] The control manager 915 may receive a downlink control information message from the base station, the downlink control information message indicating, for each resource block set in the group of resource block sets, a communication direction for the resource block set.

[0148] The guard band manager 930 can determine the configuration of one or more guard bands between the set of resource blocks based on the received downlink control information. In some examples, the guard band manager 930 can determine the frequency size of the guard bands in the one or more guard bands based on the received downlink control information. In some cases, the frequency size of the uplink guard bands in the one or more guard bands is different in size from the frequency size of the downlink guard bands in the one or more guard bands.

[0149] The bitmap manager 935 can receive a first bitmap in a downlink control information message that indicates a communication direction for a set of resource blocks. In some examples, the bitmap manager 935 can determine the number of guard bands based on the number of bits in the first bitmap.

[0150] In some examples, the bitmap manager 935 may determine the number of resource block sets in the set of resource block sets based on the number of bits in the first bitmap or the number of guard bands. In some examples, the bitmap manager 935 may receive an indication of available resource block sets in the set of resource block sets in a downlink control information message.

[0151] In some examples, bitmap manager 935 can identify that the radio spectrum band is a shared radio spectrum band. In some examples, bitmap manager 935 can determine, for each resource block set in the set of resource block sets, whether the resource block set is available or unavailable based on the received indication.

[0152] In some cases, the indication of the set of available resource blocks is indicated in a second bitmap in the downlink control information message.In some cases, the second bitmap is received in channel occupancy time system information in the downlink control information message.

[0153] Figure 10 A schematic diagram of a system 1000 including a device 1005 supporting resource block set allocation for sub-band full-duplex operation according to aspects of the present disclosure is shown. Device 1005 may be an example of, or include components of, device 705, device 805, or UE 115 described herein.
